Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

Why Top Hat Chimney Is Accokeek’s Preferred Chimney Cap & Crown Company
Ask anyone on your street. That’s not a slogan; it’s the honest truth about how word travels in Accokeek. When Wendell and his crew show up in uniform, give you a real arrival window, and leave the job cleaner than they found it, people talk. The same names come up again and again: DuraFlex liners, Famco caps, Copperfield crowns. We carry parts that match what’s already on the flues in this part of the county, so a replacement doesn’t turn into a week-long waiting game.
Accokeek homeowners call us because we treat a chimney the way a mechanic treats an engine: we give you the unvarnished answer. If your crown can be re-coated instead of rebuilt, we’ll tell you that. If the rusted cap is cosmetic and harmless for another two seasons, we’ll say so and leave. Nobody in this town wants to be sold work they don’t need, and Wendell has run into too many of you on Saturday morning to ever make that mistake.
We answer the phone at all hours, 24/7, and it may well be Wendell himself picking up. There’s no voicemail tree and no call center. Just a live person, a straight answer, and a truck that shows up when we say it will. That’s what owning a locally-run company means.
Our Chimney Cap & Crown Services in Accokeek
Cap Installation
Uncapped flues in Accokeek don’t stay empty long. Between the mature oak and tulip poplar canopy and the Piscataway National Park boundary nearby, your flue is a furnished apartment for squirrels, raccoons, and chimney swifts. We install single-flue and multi-flue caps with proper animal screening, fastened to the flue tile so they don’t blow off in the Potomac wind. In Accokeek’s older ranch homes from the 1950s through the 1970s, the original flue tiles often measure oddly, so a stock cap from a box store won’t fit right. We measure and fit on site.

Cap Replacement
A rusted-out cap isn’t just ugly; it’s an open invitation. When the mesh tears and the metal corrodes, you’ve lost the barrier that keeps rain and animals out. In Accokeek’s humidity, metal components degrade faster than they do even a few miles inland in Clinton or Fort Washington. On a split-level off Livingston Road, our crew recently replaced a rusted Famco single-flue cap on a 1970s ranch where a squirrel had nested in the exposed flue. Wendell re-fitted the cap the same afternoon, and the squirrel found other lodging.

Crown Repair
Here’s the problem with Accokeek’s location: the Potomac River floodplain means above-average year-round humidity, and that humidity works into mortar joints, opens hairline cracks, and freezes and thaws through every Maryland winter until your crown looks like a sidewalk after twenty Novembers. We repair crowns by grinding out the damaged mortar and re-forming the surface, or with a flexible crown coating that breathes with the temperature swings. If the crown’s spalled badly enough that water is getting behind the liner tiles, a rebuild is the honest fix. We’ll show you the damage on camera before we touch anything.

Crown Coating
For crowns that are structurally sound but weeping, a crown coating is the smart play. We use a flexible, brushable sealant that moves with the chimney’s expansion and contraction, sealing fine cracks before they become wide ones. In Accokeek’s humid summers and cold, wet winters, that flexibility matters more than most people realize. The $600 coating you buy today is a lot cheaper than the $1,400 crown rebuild you’ll need in three years if you ignore the early warnings.

Trusted Brands We Service in Accokeek
We work with the brands that have earned their reputation in Maryland’s climate: Famco caps, Copperfield covers, DuraFlex liners, and HeatShield coatings. We keep common parts stocked for Accokeek customers, so a standard cap replacement is usually same-visit, not next-week. If you already have a specific cap or crown brand in place, bring the old one up when you call. Chances are we’ve seen it before, and we can tell you whether a repair makes sense or whether you’re better off replacing it for less.
Common Chimney Cap & Crown Problems We See in Accokeek Homes
- Spalled mortar crowns from Potomac humidity. Accokeek sits in the Potomac River floodplain, and that moisture works into mortar joints for months at a time. A crown that would last thirty years in Clinton crumbles in twenty here if it’s not sealed.
- Chimney swift and racoon nesting in uncapped flues. The protected swifts around Piscataway National Park don’t pay rent, and they’re federally protected. That means a nest can’t be disturbed until they leave, so cap installation has to happen before they move in.
- Rusted metal caps from years of river fog and rain. We see caps that look like they’ve been through a maritime winter, because they have been. The damp air off the Potomac eats cheap metal faster than people expect.
- Cross-contamination between shared or adjacent flues. Older colonials with side-by-side flue tiles sometimes vent a neighbor’s wood stove into your unused chimney. A properly fitted cap solves the smell and keeps their smoke where it belongs.

FAQs - Chimney Cap & Crown in Accokeek
Accokeek sits closer to the Potomac River, and that’s the whole story. The floodplain location means constant moisture in the air, and that moisture seeps into the porous mortar of your crown. Freeze-thaw cycles every winter expand the water, crack the crown wider, and accelerate the spalling. A crown in Accokeek can lose five to ten years of life compared to one just a few miles north simply because of the humidity. Call (240) 358-4452 for a free crown inspection while you’re thinking about it.
A properly fitted cap with directional screening can prevent smoke from the neighbor’s adjacent flue from entering your unused chimney. Shared or closely spaced flue tiles in older colonials are common in Accokeek, and the smoke rises from their flue, then gets pulled back down into yours. The right cap changes the airflow so their smoke goes up and away, not sideways into your house. We’ve fixed this exact problem in homes off Indian Head Highway, and the fix is usually a single custom cap.
Yes, and here’s why: chimney swifts are federally protected migratory birds, and the population around Piscataway National Park is dense. If swifts are actively nesting in your flue, we can’t legally disturb the nest until the young have left. That means the cap has to be installed before they arrive in spring, not after they’ve moved in. If you call us in early March, we can cap the flue before nesting season starts and spare you a summer of waiting.
Once a year, burn or no burn. Chimneys break in the off-season too, and our Accokeek humidity doesn’t take the summer off. An annual inspection catches hairline crown cracks before they widen, rust before it becomes a hole, and nesting attempts before they become a federal matter. The inspection is free when you combine it with a sweep, and the camera footage is part of the service.
Indirectly, yes. Water entering through a cracked crown doesn’t create creosote, but it makes the flue interior cool and damp, which causes more creosote condensation when you burn. That dark, tarry third-degree glazing is far more common in damp, water-damaged chimneys than in dry ones. The fix is a two-step approach: repair the crown to stop the water, then remove the glaze. First-degree creosote is a brush job. Third-degree is a glaze, and it’s a fire risk you don’t want to sit on.
